SPECIFICATION forming part of Letters Patent No. 739,958, dated September 29, 1903. Application filed October 1'7, 1902- Serial No. 127,685. (No specimens.)

To all whont it'naay concern:

Be it known that I, BENJAMIN J. WALKER, a citizen of the United States, residing at Erie, in the county of Erie and State of Pennsylvania, have invented new and useful Improvements in the Method or Process of Burning Pulverized Goal, of which the following is a specification.

This invention relates to the method or process of burning pulverized coal; and it consists incertain improvements therein, as will be hereinafter fully described, and pointed out in the claim.

The purpose of the invention is to provide a method of burning pulverized coal wherein a proper combustion may be attained and the formation of coke and smoke obviated. I,

. be used, as follows:

Figure 1 shows a section on the line 1 l in Fig. 2. Fig. 2 shows a section on the line 2 2 in Fig. 1.

A marks the furnace, which is provided with the ordinary bridge-wall B. Mounted on the furnace is the boiler O. The gas is passed over the bridge-wall, through the boiler, and out the stack D, as commonly. Pulverized coal is delivered under blast through pipes E, entering the furnace at the points 6 e. The

points 6 e are directly opposite, and the direction of the pipes E is directly opposite as they enter the furnace. The blasts from these pipes meet at the center of the furnace,

and the fuelthrough this action is scattered and held momentarily'in suspension, during which perfect combustion takes place and no object is so cooled by the blast as to prevent proper combustion.

What I claim as new is- The process or method of burning pulver- 5o ized fuel which consists in delivering pulverized coal with opposing blasts so directed and of sufficient force to spread the fuel by impact of the opposing blasts in all directions from the point of impact in a plane approxi- 5 5 mately at right angles to the blasts and keeping the fuel in suspension during combustion. In testimony whereof I have hereuntoset my hand in the presence of two subscribing witnesses.
